1. General
Thank you for purchasing an Xpelair Xcell Wholehouse heat recovery unit. We have paid a
great deal of attention to the design of this unit and have only used high quality,
recyclable materials in its manufacture which is powered by energy efficient EC/DC
motors.
This system is designed to run 24 hours a day.
The Xcell unit is the centre of a balanced supply and extract ventilation system. Other
products available from Xpelair include, flexible, flat and slim ductwork, and a 3-speed
switch.
In certain circumstances it is possible to connect a fan-less kitchen cooker hood into the
system.
This guide is intended as a reference manual for the fitter, so that he can install and
correctly maintain the unit. Please read this booklet thoroughly before installing the unit.
In the unlikely event that you have to contact our offices please quote the type of unit,
order number, and date of manufacture.
1.1 Configuration
The Xcell unit has been designed for extracting stale air from a dwelling and replacing it
with fresh filtered air.
The Xcell units are available in 4 configurations
1. Xcell 300; duct connections to the house on the right and external duct
connections on the left.
2. Xcell 300BP; duct connections to the house on the right and external duct
connections on the left.
This unit is complete with an automatically regulated by pass damper.
3. Xcell 400; duct connections to the house on the right and external duct
connections on the left.
4 Xcell 400BP; duct connections to the house on the right and external duct
connections on the left
This unit is complete with an automatically regulated by pass damper.

2 Installation
View - looking at the top of the unit
The Xcell unit must be placed in a frost-free space.
Close to the unit there must be a 220/240 Volt fused spur (with earth), a suitable
connection for the condensate drain and sufficient space to connect the duct runs to the
heat recovery unit.
If the unit is to be fixed to a wall/partition the unit must be installed using the hanging
bracket provided. The wall should be structurally rated to accept a weight of 200Kg per
square meter.
The unit must be installed horizontally (with the spigots at the top). A spirit level should
be used to make sure that it is straight.
Enough space should be left to allow a significant slope for the condensate drain to
ensure correct evacuation of the water.
A minimum space of 800 mm is needed at the front of the unit to open the access door and
change the filters.
Connect power supply after assembling the ducting!
2.1 Regulations
Where applicable installation of the unit must comply with all local regulations including,
building, electrical and sewerage connections.
2.2 Mounting the unit
The Xcell unit can be placed on a floor or attached to a
wall with the hanging bracket provided. If floor
mounted, assemble the unit so that sound and vibration
transfer is avoided and there is sufficient height for the
condensation drain. If wall mounted secure the unit by
using the bracket provided. The wall or partition should
be at least 100 mm thick.
Unpack the unit and place it on the ground. Unbolt the
metal lid on the top of the unit and remove it. Turn the
nut separately and remove the hanging bracket. Fix the
hanging bracket to the wall/partition. Use a spirit level to
make sure the bracket is level.
2.3 Connect the ducting
To avoid condensation ductwork inside the loft space must be insulated.
It is recommended that that insulated acoustic flexible ducting be used with a minimum
length of 1 metre on the external sides of the unit and a minimum length of 500 mm on
the internal side.
Where possible the air intake to the building should be sited in a sheltered area.
Supply and extract to and from the house can be through roof terminals or louvres.
To make sure there is no re-circuiting of polluted air a minimum of 2 metres should be
allowed between the supply and discharge terminals.
To allow free airflow through out the house a gap beneath the doors must be provided
(or grilles put at low level in the doors)
2.4 Positioning extract and supply valves
Extract grilles should be placed in all wet rooms in accordance with the Building
Regulations and supply valves in all the heated rooms. Extract grilles should be sited
close to the main source of humidity.
Care should be taken not to create drafts in sensitive areas of the house e.g. bedrooms,
etc.
2.5 Connect condensation evacuation.
The condensation drain is in the lower part of the unit.
In a Right-handed unit the left hose connection must be used.
The hose fitted to the condensate drain must have an internal diameter of 12 mm and a
minimum length of 1.5 metres.
2.5.1 The drain should run through a secondary trap before being discharged though the
eaves of the house or into the waste water systems (check local regulations).
2.6 Speed control
The cable between the Xcell 300/Xcell 400 and the 3-speed switch must be 4-core with a
minimum thickness of 0.14 mm.
The connections are to a connector under the top plate of the unit. To make the
connections easier the plug is removable.
When replacing the unit top plate it is important to make sure there are no air leaks, as
this will affect the performance of the product.
The cables must be connected to the correct terminals or the unit will run at incorrect
speeds or the unit may be damaged.
For correct connections of the 3-position switch see the wiring diagram.
The speed control is low voltage and must not be connected directly to a 230
volts power supply.
2.7 Fire alarm contact
It is possible to connect a volt free fire alarm contact to the unit.
The fire alarm contact must be connected to the P and BM of the 5pole connector. If the
contact is made, the supply fan will stop and the extract fan will run at maximum speed.
2.8 Power supply
The unit must either be wired to a suitably earthed 230/240-volt single-pha se 50 Hz fused
spur or to a standard 3 pin 13 -amp socket.
The electric installation must be in accordance with the requirements of the local electrical
regulations.
2.9 By-pass
The Xcell unit with by-pass is factory installed and programmed by Xpelair. There is an
extra bypass circuit in the connection box, and one in the by-pass cassette. These circuits
automatically control the opening and closing of the by -pass. The room and outside
temperatures are detected by two sensors, which are fitted inside the unit.
The temperature sensors have been fitted to the bypass module. The sensor fitted to the
lower part is the room temperature sensor (red) and the sensor to the upper part is the
outside air temperature sensor (blue).
By-pass open when:
The room temperature is above 20 °C. (LED 1 = on) and
the outside temperature is under the room temperature (LED 2 = on) and
the outside temperature is above 15 °C (LED 3 = on).
By-pass closed when:
The outside temperature is above the inside temperature or
The outside temperature is below 15 °C or
The inside temperature is below 20 °C.
Temp 1 = room temperature sensor.
Temp 2 = outside temperature sensor.
LED 1 = room temperature.
LED 2 = difference between outside and
inside temperature.
LED 3 = outside temperature.
LED 4 = By-pass closed.
LED 5 = By-pass open.
LED 6 = By-pass active.
LED EXT = for connection to a remote
LED (not supplied).
3. Commissioning the system
3.1 Setting the air volume
The unit is provided with 3-step regulation. The supply and extract fan run
independently of each other and are individually programmable.
3.2 Fan speed adjustment (Figure 1)
The extract fan can be adjusted with the 3 red potentiometers that are marked AV and the
supply fan by those marked TV.
When the speed settings are changed the system must be rebalanced ensuring that the
supply and extract air flow are similar. This is to protect the heat exchanger from any
possible damage.
Standard settings for the Xcell 300 are 100, 150 and 300 m³/h
Standard settings for the Xcell 400 are 100, 200 and 350 m³/h

5 Maintenance
5.1 User maintenance
Clean the filters (with a vacuum cleaner) twice a year and the air vent grilles wiped clean
every 6 months.
The two filters can be taken out by the handgrips
.
5.2 Specialist maintenance
The heat exchanger must be removed and cleaned every 3 years.
Remove the filters. Unscrew the front panel (two screws). Remove the cover plate.
Where there is a by-pass, disconnect the plugs on the board. The heat exchanger is now
accessible. Remove the four rubber gaskets and take the heat exchanger out.
Clean the exchanger, with warm water and a normal
soap (no solvents).
Then rinse with warm water.
Reassemble the unit (reverse of dismantling) making
sure all components are correctly refitted ensuring there
are no air leaks.
If the fans are dirty they must be cleaned with a brush
and vacuum cleaner.
